HlNGE' FOR AWNING-BLINDS.

SPECIFICATION forming part of Letters Patent No. 231,655, dated August31, 1880. Application filed April 23, 1880. (Model) 10 all whom it mayconcern:

Be itknown that I, CHARLES P. DEARBORN, of Boston, county of Suffolk,State of Massachusetts, have invented an Improvement in Blind-Hangings,(Case 13,) of which the fol lowing description, in connection with theaccompanying drawings, is a specification.

This inventioi'l relates to improvements in blind hangings or hinges ofthat class which permit the blinds to swing separately about a verticalpivot, or both turn out at bottom on horizontal pivots at the tops ofthe blinds to permit the blinds to serve as an awning.

In a patent of the United States heretofore granted to me, No. 202,935,I have shown and described a lower hinge the socket portion of which ismade vertically movable, so as to remove the said socketed part from thehingepintle when it was desired to turn outward the bottom of the blindto enable the blind to serve as an awning, the entire weight of theblind during such operation resting upon the upper hinge.

My present invention is an improvement on the hinge described in thesaid patent, and relates, chiefly, to providing a hinge of this classwith lockin g devices to prevent it from being lifted or disengaged fromthe pintle by a person outside the house. I have also shown the saidsocket portion pivoted on a stud, so as to move in the arc of a circle,which makes a stronger, more easily operated hinge, and one of lesscost.

the other figures; and Fig. 8, a detail of part of the lower hinge, toshow more clearly the provision herein made to lock the blinds open whenthe blinds swing, as usual, on the vertical pintles.

In the drawings, (it represents the casing or fixed part of thebuilding, and b the side rail of a blind.

The upper hinge, c (1 cf, is as in my patent referred to, c carrying theupper pintle, d being attached to the blind, the socket 6 beingconnected loosely with part (I by a pivot,f, as in Fig. 3. The meinbergofthe lower hinge, to be attached to the casing or building, has apintle, h, and a lateral projection, with a fastening-stud, i, or notch,and a stop,j, to prevent the blind being accidentally lifted from theupper hinge. That member of the lower hinge to be connected or move withthe blind is composed of a plate, 70, having holes 2 to receive screws,by which to attach it to the blind, and of a movable socket part, 1,

preferably pivoted to the part It; by a pivot, 3, so that the saidsocketed portion may be turned in the arc of a circle when being liftedfrom the pintle. This socketed part has one part of it (marked m)prolonged to form one portion of the socket-part locking device, theother co-operat-ing part being arnovable stop, a.

In Figs. 1 to 6 thcpart m is made as a hook, and the part it as asegmental plate pivoted at '4, and having a pin, 5, by which to turn theplate. When the platen is as in dotted lines, Fig. 1, the socketed partcannot be lifted or moved from its engagement with the pintle from theoutside of the blind; but when as in full lines, Fig. l, the socketedpart may be turned on the pivot 3 and lifted or removed from the top ofthe pintle, to permit the lower endof the blind to be turned outward, asin Fig. 3.

The socket part I has a handprojection, 0, to be grasped by the personopening the blind, if it is desired to detach the socket portion fromthe pintle. Extendingfrom thelowerend of the socket portion is a shortarm, 1), which, when the blind is opened, falls behind the projection2', before referred to, of the fixed member g, or into a notch in thesaid member,'to

hold the blind open when swung outward on the vertical pintles. When theblinds are to be closed from the inside the plate a or n is disengagedfrom the socketed part Z, permitting the latter to be lifted just farenough to elevate the projection 12 above the projection 2'. Thisobviates lifting the blind when it is to be unfastened an d closed,which is customarily done in blinds now commonly in use of the CharlesParker class, such lifting of the blind to enable it to be closedresulting very frequently in lifting it a little too far when the blindis thrown from the building.

The device for holding the two blinds together when being used as anawning may be of any usual construction.

In Fig. 7 I have shown a modification illustrating the application of alocking device for the socketed part when the same is slotted, as at 6,to slide vertically on pins 7, as illustrated in my patent referred to.In the said figure the movable member of the locking device (thereindistinguished by the letter W) has a slot to permit it to be guided byand turn on apin, 8, when,as in full lines, the part a meets the upperpart of the movable soeketed member and looks it, so that it cannot belifted; but when in the position shown in dotted lines the socketed partmay be freely lifted from the pintle.

I claim 1. The pintle member g, provided with the projection '13,combined with the socket portion 1, made detachable from the pintlewhile the weight of the blind is supported by the upper hinge, andprovided with a projection), to cooperate with the projection of thefixed member g, to hold the blind securely when opened, substantially asdescribed.

2. In a hinge for awnin g-blind s, the plate It and the socket portionZ, pivoted thereon, as described, and provided with the hand-projectionlocated at the inner face of the blind, to permit it to be turned aboutthe pivot 3 and disengage the socket from the pintle, whilet-he upperhinge supports the weight of the blind, in combination with the blockingdevice, to cooperate therewith and prevent the socket part from beinglifted from the pintle, as set forth.

3. In a hinge for awning-blinds, the plate It and socket portion Z,pivoted thereon, provided Willi the hand-projection 0, located at theinner face of the blind, substantially as described.

4. In a hinge for awning-blinds, the plate k and socket part I. pivotedthereon, provided with a handle portion, 0, and hooked projection 112,combined with the movable plate, to engage and hold the said hookedportion m, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES P. DEARBORN.
